Kim K. Exclusive: Pregnancy is Hard

BREAKING: Details from Inside Kimye's Evening at Chateau de Versailles

Entertainment Tonight's Christina McLarty was the first to catch up with Kim Kardashian in Las Vegas at her first appearance since her boyfriend, rap star Kanye West, announced that they are expecting a child together.

Kardashian tells ET that pregnancy is harder than she imagined and the changes to her body are difficult. She also tells McLarty that she is taking a lot of naps.

"I wouldn't say it's been easy," she said. "When people say that pregnancy is fun and they love it I would have to disagree. Even my sister has made it look easy, but it's not as easy as people think. I heard it's all worth it so I'm looking forward to that."
